    • Define the ERP source to integrate with Coupa
    • Create a basic authentication profile using Coupa integration credentials for web service access
    • Associate the authentication profile with service maps
    • Define source configuration to specify the ERP system connection

    Practical Benefits

    By configuring ERP Source for Coupa, ServiceNow customers enable automated, real-time synchronization of critical procurement and financial data between Coupa and their ERP systems. This reduces manual data entry, increases data accuracy, and supports multi-ERP environments with clear source identification. The flexible service map customization allows adaptation to specific organizational requirements.

    Configure your Source-to-Pay (S2P) instance to support inbound and outbound integration with your ERP system. This integration configuration enables you to post purchase order, receipt, invoice, and download primary data from the ERP automatically.

    ERP source configuration enables the implementation of a specific logic to populate values relevant to third-party ERP systems. The configuration includes all service mappings defined between Source-to-Pay (S2P) and the third-party ERP system. In cases where multiple ERP sources exist, they’re stored as distinct ERP source entries with their corresponding service mappings.

    To meet specific requirements, you can modify the service-mapping logic by updating the relevant service element map entry within the service map record. For organizations using multiple ERP systems, an ERP Source field has been incorporated into the tables to ensure accurate identification of the respective integrated ERP system.

    The ERP source configuration for Coupa enables customers to establish multiple Coupa instances. Each instance is identified by a distinct source, and the connection alias for each instance must be unique.

    Prerequisites

    Before you start the integration configuration, you must get the following details from the ERP team:
    • ERP integration user credentials.
    • SOAP or REST API details based on your ERP system and the type of web services you’re using for the integration.
    • Roles to be added for the Integration users.
